[mpich-discuss] Missing Nemesis ib

[Jason Collins]

I ran the test and the result was the following:

# ./mxm_perftest

[1505976675.346380] [compute1:55801:0]         sys.c:744  MXM  WARN
Conflicting CPU frequencies detected, using: 3600.52

Waiting for connection...


It does nothing else, it remains waiting to establish connection.
